JTS Airacuda Max leak from barrel entry

I have the same problem on my Airacuda Max. I tried contacting the company 2 times and still no resonce.
Does anyone know where I can find instructions on how to fix it myself?
I sent a 3rd email. I told them I had already sent 2 requests, with no response. Therefore, I was going to pack it up, ship it back. Either fix it or keep it, because to me it is just a paper weight as it is. The next day I got a return email with RMA for return. Once I get it back, just going to sell it. I have already replaced it.

If you had air coming out of the barrel that means that the valve and poppet are not sealing against each other.
I had air coming out the barrel and I had to burnish the valve.

There is an entire thread about that here: https://www.airgunnation.com/threads/jts-airacuda-likes-balloons.1321499/
